mail record to one ip and mx to another

Can I have mail.domain.com.au point to local server IP and MX.domain.com point to hosted exchange with a different ip.Will this stuff up my email delivery?

What happened was, I started email migration using mail.domain.com as the source, but now that have a dns change to mx.doma.com, i can't continue the migration because there is no longer a mail.domain.com.

So if i add a mail.domain.com back to the server IP and keep the MX.domain.com to the new mail server. will this cause email problems.

Thanks in advance.

i forgot to mention mail.domain.com is a A record and mx.domain.com is an MX record.

The short answer is, yes. A domain's MX record tells the internet where to send mail for that domain. An MX record references an A record, but it does not have to be the A record for the mail server. Often, companies will have incoming mail delivered to a spam filter, which then delivers to the mail server.

The email trouble you might have is with internal clients -- if they are looking for incoming mail at mail.domain .com, it won't be there unless it is being forwarded there by MX.domain.com
